Finally got around to doing mine this morning.
Avo's post reminded me I had some spare pond liner rubber lying around so I used that.
Riding through the village at 30mph is possible now without the bike shaking itself to bits. MUCH smoother than it was before.
When I took the wheel off I noticed some furry corrosion around the spindle hole in the swing arm.
This is what I found when I took out the chain adjusters.
Lots of corrosion and salt crystals
The one on the left has been wirebrushed. I coated them with grease before refitting.
